Definition
Cataclasite is a type of cataclastic rock that is formed by fracturing and comminution during faulting. It is normally cohesive and non-foliated, consisting of angular clasts in a finer-grained matrix
Lamprophyre is uncommon igneous rocks primarily occurring as dikes, lopoliths, laccoliths, stocks and small intrusions

Archaeological Significance
Formation
Cataclasiste rocks mainly form by pressure deep under the Earth's surface, from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.
Lamprophyre formation takes place deep beneath the Earth’s surface at around 150 to 450 kilometres, and are erupted rapidly and violently.

Cataclasite vs Lamprophyre Characteristics
Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Cataclasite vs Lamprophyre characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Cataclasite and Properties of Lamprophyre. Learn more about Cataclasite vs Lamprophyre in the next section. The interior uses of Cataclasite include Decorative aggregates and Homes whereas the interior uses of Lamprophyre include Decorative aggregates and Interior decoration. Due to some exceptional properties of Cataclasite and Lamprophyre, they have various applications in construction industry. The uses of Cataclasite in construction industry include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate and that of Lamprophyre include As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories.
More about Cataclasite and Lamprophyre
Here you can know more about Cataclasite and Lamprophyre. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Cataclasite and Lamprophyre consists of mineral content and compound content. The mineral content of Cataclasite includes Albite, Apatite, Augite, Biotite, Calcite, Enstatite, Epidote, Feldspar, Micas, Muscovite or Illite, Pyroxene, Quartz and mineral content of Lamprophyre includes Amphibole, Carbonate, Garnet, Micas, Olivine, Phlogopite, Pyroxene. You can also check out the list of all Metamorphic Rocks. When we have to compare Cataclasite vs Lamprophyre, the texture, color and appearance plays an important role in determining the type of rock. Cataclasite is available in brown, green, white, yellow colors whereas, Lamprophyre is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors. Appearance of Cataclasite is Dull and Banded and that of Lamprophyre is Dull, Banded and Foilated. Properties of rock is another aspect for Cataclasite vs Lamprophyre. The hardness of Cataclasite is 3-4 and that of Lamprophyre is 5-6. The types of Cataclasite are Protocataclasite, Mesocataclasite, Ultracataclasite and Foliated cataclasite whereas types of Lamprophyre are Minette, Alnoite, Camptonite, Monchiquite, Fourchite, Vogesite, Appinite and Spessartite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Cataclasite is black while that of Lamprophyre is white. The specific heat capacity of Cataclasite is 0.84 kJ/Kg K and that of Lamprophyre is 0.84 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Cataclasite is heat resistant, impact resistant, pressure resistant whereas Lamprophyre is heat resistant, impact resistant.
